Is UTC or local time used with time-based notifications?

I have a time in the future when I want a notification to occur and need to know if ::CeSetUserNotification开发者_运维技巧Ex expects UTC or local time in the stStartTime field of the CE_NOTIFICATION_TRIGGER structure if the dwType field is set to CNT_TIME?

After actually testing ::CeSetUserNotificationEx with both UTC and local time input, I'm in the position of answering my own question:

::CeSetUserNotificationEx wants local time.

Use ::GetSystemTime() to fill up your stStartTime param, convert it to FILETIME through ::SystemTimeToFileTime(), cast the resulting FILETIME structure to a ULARGE_INTEGER structure, add the relevant milliseconds interval, cast back to FILETIME, convert to your stEndTime param with ::FileTimeToSystemTime().
